What if I changed the proportions of the basic block from 2:1 to 3:1? (I'll confess this was an accident, I had 6-1/2" in my head, the finished block size, rather than the 4-1/2" I was supposed to cut the rectangular pieces; but hey, I think it worked).

And what if I bisected both the square and rectangular pieces with a center pinstripe? What if I put the pinstripe just in the squares? What if I angled the stripe rather than making it straight and centered? What if I mixed up all those variations in one panel?

What if I used my machine's 3-step zigzag stitch and flattened and elongated it to make an interesting line, and used that for an allover quilting design? (This is an idea I got from a Craftsy.com course taught by Jacquie Gering, have been wanting to try it so why not now?)
